Inspiron 1525 Battery Replacement

Hi,

I Have a Inspiron 1525 laptop and it has started displaying a message when I switch it on telling me I need a new battery.

I know my current battery has the following details:

- Li-io

- Rating 11.1v

- Capacity - 41wh

- Type MG119,GW240, RN873, GP952, X248G

I got a new battery for it before but it was too big in size and it caused the fan in the laptop to get damaged, so i am a bit nervous buying a new one. I have found a battery which is a Li-io battery, has 6 cells, is 1.1v, is 5200mah and says its compatible with DELL 312-0625 312-0633 312-0763 451-10478 451-10533 C601H D608H GW240 HP297 M911G RN873 XR693 GP952 RU586 RN873 WK379 X284G XR693 312-0626 312-0634

I am unsure as it does say what the capacity is in wh and I also do not know how many cells my current battery has. It does seem compatible in rating, type and battery type. I need some advice, is battery compatible my laptop?

Thanks

Jeskit
